SUPERPLASTISTICIZER BASED ON SURFACE-MODIFIED MINERAL NANOPARTICLES FOR MORTAR AND CONCRETE |
摘要 |
<p>The invention relates to a superplasticizer for a cementitious composition, such as cement paste, mortar or concrete, characterized in that it is in the form of surface-modified particles constituted of mineral nanoparticles covered with a polymer coating formed predominantly of polyalkyl oxides. It enables a good fluidity to be maintained, without retardation of setting, and also gives the mortar or concrete composition anti-shrink properties.</p> |
